I recently put on the MBRP Race and I haven't had any problems with drone so far, I've heard it has some drone at 1,800 rpms but since I've got the manual I can avoid that pretty easily. I'm not sure if it would have more in the automatic but I LOVE the sound so far.
One of the people on youtube that I watch had the Corsa Extreme Catback Exhaust and the Kooks Catless Headers but said they were too loud on a daily driver, even for him. Can anyone chime in on how the Corsa Extreme and Catless headers go together on a daily driver? Any drone? Thanks!
